Quick verdict

Pick Google Calendar if you share schedules with others. Pick Tiimo if you plan alone and want a visual timeline with AI task breakdown.

Google Calendar is free with a Google Account on web, Android and iOS. It is wired into Gmail, Meet and Tasks and offers five sharing permission levels. Gemini scheduling help needs a Workspace plan, and your data falls under Google's company-wide privacy policy.

Tiimo is a timeline planner built for people with ADHD, autism or time-estimation difficulties. It has a free mobile tier, but its pricing page lists no amounts, charges are generally nonrefundable and it has no team features.

Choose Google Calendar if…

  • Choose Google Calendar if you want a simple booking page at no cost.

Choose Tiimo if…

  • Choose Tiimo if you have ADHD or often lose track of time.

  • Choose Tiimo if you use iPhone and Apple Watch and like widget and Live Activities reminders.

Two different ideas of a day

Google Calendar is built around events: meetings, flights pulled from Gmail, free/busy blocks others can see. Tiimo is built around getting things done: a morning shows as coloured blocks, each task has a timer, and AI splits big jobs into steps. So the two need not compete. Someone could keep appointments with others in Google Calendar and use Tiimo to walk through their own day. Note that the data reviewed lists no Tiimo integration with Google Calendar.

Hidden costs and easy-to-miss limits

Google Calendar is free, but according to 9to5Google (June 2023) personal accounts get only one booking page, and automatic reminder emails need a paid plan. That page must also be built in a desktop browser. Gemini scheduling needs Workspace. Tiimo's costs are harder to predict: no amounts on the pricing page, a 7-day yearly trial that requires a card, and charges generally nonrefundable even for unused time. App Store subscribers must ask Apple for refunds themselves.

Reading the Tiimo complaints in context

All seven reviews on a Trustpilot profile for Tiimo are 1-star, alleging post-trial charges, slow support (one waited 10 days), missing reminders and lost data. These are allegations no authority has confirmed, and Tiimo hasn't claimed the profile. Set against 21,000+ App Store ratings averaging 4.6/5 and Apple's iPhone App of the Year 2025 award, they are a signal to watch rather than a verdict.

Where your data goes

With Google, your calendar is one piece of an account-wide profile covering location, activity logs and interest-based ads, balanced by export, deletion and auto-delete tools; on work accounts, admins may see your calendar. Tiimo, a Danish company under GDPR, keeps data up to two years after cancellation and may process it outside the EU/EEA under Standard Contractual Clauses. The open question is what you tell its AI and mood tracker: the policy says nothing about either.

Frequently asked questions

Can I use Tiimo on a computer?

Yes, there's a web app, but only during a trial or with Tiimo Pro. The free version runs only on the iOS and Android apps.

Do they support Vietnamese?

Yes, Vietnamese is among the interface languages of both apps.

What do I need for Gemini in Google Calendar?

An active Workspace plan. The cheapest Workspace plan listed is Business Starter at $7/user/month on a 1-year commitment, before tax; the data reviewed doesn't specify which plans include Gemini.

Will Tiimo refund me if I cancel mid-period?

Tiimo's FAQ says generally not, including unused time. For web or Google Play purchases, contact [email protected] or the site chat; for App Store purchases, ask Apple.
